- W2020407861 abstract "We report the case of an healthy 7-month-old infant with no known pathology, who was brought to the pediatric emergency department for sudden appearance of erythematous and fluctuant vulvar tumor (Figure 1). Tumor reduction was conducted, while observing its urethral origin. Bladder ultrasound was performed; the presence of an intravesical sac adjacent to the right lateral bladder wall supports a ureterocele. The study was completed with intravenous urography and magnetic resonance imaging, showing the right dual system with a ureterocele of 1.5 cm × 1.6 cm and a hydronephrotic and nonfunctioning right upper pole (Figure 2). Cystography showed the absence of vesicoureteral reflux. We performed upper right polar heminephrectomy with partial ureterectomy and ureterocele aspiration.Figure 2Nuclear magnetic resonance showing ureteral duplication in the right kidney upper pole.View Large Image Figure ViewerDownload Hi-res image Download (PPT) A ureterocele may occur in a normal excretory urinary system or with ureteral duplication. When a ureterocele is not associated with ureteral duplication, it can often overlooked because it is not usually associated with symptoms. However, when it is associated with ureteral duplication, there usually is obstruction and infection of the kidney that drains the upper pole.1Calleja Aguayo E. Delgado Alvira J. Elías Pollina J.

Delgado Alvira J. Elías Pollina J. Romeo Ulecia M. González Esgueda A. Esteban Ibarz J.A. Cir Pediatr. 2010; 23: 28-31PubMed Google Scholar The therapeutic management of ureterocele differs depending on whether there is ureteral duplication and vesicoureteral reflux or obstruction. In mild cases, without an ectopic ureter and without vesicoureteral reflux, the endoscopic management is a valid option with good results and lower risk of retreatment.5Pohl H.G.
